[SOLVED] How to customize host client name in proxmox-backup-client

[Fra]

I use proxmox-backup-client to backup my laptop in my personal PBS

I recently "formatted" my laptop and want to keep doing backups on the same backup group (host/mylaptophostname): this is not possible since I've set a new hostname to my laptop, so Pbs created a new backup group host/mylaptopnewhostname.



I've read the doc at https://pbs.proxmox.com/docs/backup-client.html but cannot figure how to set a custom host client name

this is the script

export BACKUP_USER='redacted@pbs'
export PBS='[IP of pbs]'
export PBS_FINGERPRINT='redacted'
export DATASTORE='local-storage'
export PBS_PASSWORD='redacted'
export PBS_REPOSITORY=${BACKUP_USER}@${PBS}:${DATASTORE}
/usr/local/sbin/proxmox-backup-client backup etc.pxar:/etc  home_documents.pxar:/home/redacted/Documents/

Modify your script and at the first line put

hostname mylaptophostname


and the last line

hostname mylaptopnewhostname

uh, nice hack
it works

there is an issue: during the backup (which last hours) the laptop has e new (wrong) hostname

maybe I should have a look at the proxmox-backup-client source code (where is it? I cannot find it in https://git.proxmox.com/) to see if the hostname comes from the `hostmame` command or there is something else in between

No, sorry, this was a little work for you but i suggest a solution


hostname myoldname
export BACKUP_USER='redacted@pbs'
export PBS='[IP of pbs]'
export PBS_FINGERPRINT='redacted'
export DATASTORE='local-storage'
export PBS_PASSWORD='redacted'
export PBS_REPOSITORY=${BACKUP_USER}@${PBS}:${DATASTORE}
nohup /usr/local/sbin/proxmox-backup-client backup etc.pxar:/etc home_documents.pxar:/home/redacted/Documents/ &
hostname mynewname

Can this be sufficient?

Just a question: how many TB do you have on your laptop?

> Just a question: how many TB do you have on your laptop?

the backup is about 100G (changes are minimal), with a pretty bad upload bandwidth.

you can just specify the backup ID (which defaults to the hostname for host-type backups) as option when calling proxmox-backup-client):

https://pbs.proxmox.com/docs/terminology.html#backup-id
https://pbs.proxmox.com/docs/command-syntax.html#proxmox-backup-client

ah, fantastic!

so, I replaced

/usr/local/sbin/proxmox-backup-client backup etc.pxar:/etc  home_documents.pxar:/home/redacted/Documents/

with

/usr/local/sbin/proxmox-backup-client backup etc.pxar:/etc  home_documents.pxar:/home/redacted/Documents/  --backup-id mylaptophostname

thanks fabian
